Root metabolome variation analysis and top 15 metabolites for the PC1 and Comp 1. a Principal component analysis (PCA) of root metabolome variation among samples and the top 15 metabolites contributing to the PC1; (b) Partial least squares discriminant analysis (PLS-DA) of root metabolome variation among samples. PC1: the first principal component; PC2: the second principal component; Comp1: component 1; C: control; LK: low potassium; R: root (n = 6)
